Patented Oct. 8, 1935 STATES PATENT OFFCE 8 Claims.

This invention relates to improvements in slippers and more particularly to the soft-soled type of slipper and the method of making the same.

My Patent Number 1,916,067, dated June 27,

i i933, discloses a, slipper in which the upper, sole and sock lining are secured together by a ro-w of stitching and a padding inserted between the sole and lining. Some difculty has been experienced in introducing the padding into the space between said sole and lining. In 4accomplishing this operation a pronged implement has been employed to force the padding into position. It has been found that the prongs of said implement have a tendency to displace the fibers of the padding and cause the same to bunch in the toe of the slipper so that an uneven surface is formed.

. The present invention is designed primarily to overcome the above diiiiculty by providing-the padding with a pocket into which a flat implement may be inserted and engaged with the toe end oi 'the padding so that the latter can be readily forced into the space between the sole and sock lining and positioned therein in a perfectly flat condition.

The invention further contemplates a padding in which two superimposed layers of material are secured together for portions of the lengths thereof, with the remaining portions unattached to each other so that the shank stiifener of the slipper may be positioned between the latter portions with one of them thus overlying the stiifener and interposed between the same and the foot of the wearer.

The inventive idea involved is capable of receiving a variety of expressions one of which, for purposes of illustration, is shown in the accompanying drawing, wherein:-

Figure 1 is a longitudinal section through a completed slipper constructed in accordance with the invention.

Figure 2 is a similar section showing the slipper at an intermediate stage of assembly.

Figure 3 is a top plan View, partly broken away and shown in section, with the upper portion of the padding turned back so as to disclose the shank stiiener of the shoe.

Figure 4 is a section on the line 4 4 of Figure 1.

Figure 5 is a section on the line 5-5 of Figure 1, and

Figure 6 is a perspective View of the padding of the slipper.

In assembling the elements of the slipper, the same initial procedure is followed as set forth in the above-noted patent. That is, the upper 1,

the soft sole 8 and the sock lining 9 are first brought together in a reversed position from that shown in Figures l and 2 of the present drawing, and with the sole on the under side of the upper and the sock lining on the opposite side. The 5 outer edges of said three elements are then stitched together by a single row of stitches Iii and such stitches are extended rearwardly to approximately the medial point of the slipper as indicated at ii (Figure 2). Also, as in the above l0 patent, the row of stitching is continued rearwardly from the point II to secure the upper to the sole, leaving the rear portion of the sock lining free. Following this stitching operation the element-s l, 8, and 9 are turned inside out to their 15 normal positions shown in Figure 2.

The padding generally indicated by the numeral I 2 is then inserted into the space between the sole 8 and the sock lining il. In order to facilitate the insertion of said padding the same, 2o in accordance with the present invention, is made of two superimp'sed layers I3 and icl of iibrous material usually employed in slippers of this character. Said layers are of suiiicient length to cover the entire interior of the slipper and are secured together by stitching along their edges from the toe end of the padding to a point intermediate the ends thereof as indicated at I5. The remainder or rear portions of the layers I3 and I i thus remain unattached and provide an opening at the intermediate point of the padding for the insertion of a flat implement into the pocket formed by the attached forward portions of said layers. With said implement thus inserted into the pocket and engaged with the toe end of the padding, the latter may be introduced into the space between the sole 8 and lining 9 and forced forwardly by pressure of said implement until the toe end of the padding contacts the tip of the slipper. The padding is thus enabled in a iiat condition so that it will not wrinkle in the toe portion of the slipper and after it has been properly positioned the implement used to force the same into place may be withdrawn.

The next operation in the assembly of the parts of the slipper is to lay the shank stiffener I6 in position and secure the same to the heel II of the slipper by the fasteners I8. The shank stiffener I6 is laid upon the rear portion of the lower layer I4 of the padding I2 and after be- 50 ing secured by said fasteners I 8, the rear portion of the upper material I3 of said padding is then superimposed upon the shank stiifener so that the latter will be positioned between the two layers of the padding and the wearers foot to be maintained 40 thus adequately protected against any possible contact with said shank stiffener. It is also proposed to encase the rear portion of the upper layer I3 of the padding within the sock lining 9 and, for this purpose, an additional strip I9 of the same material as the sock lining is stitched thereto so as to form a pocket for receiving said portion of the padding. Said strip I9 extends forwardly from the heel to approximately the point I5 where the two layers of the padding are secured together and as a final operation in the assembly of the parts of the slipper, a suitable adhesive is applied to the under surface of said strip I9 so that it will adhere to the rear portion of the layer I4 of the padding and to the shank I6 which is superimposed upon said portion.

What is claimed is:

1. The method of making slippers which comprises securing together the upper, sole and sock lining of a slipper while said elements are in a reversed position with the upper interposed between the sole and sock lining, turning said elements to their normal position, supplying a padding formed oi two layers of material stitched together partly around their edges to provide a pocket, and forcing said padding between said lining and sole by utilizing an implement intro duced into said pocket.

2. The method of making slippers which comprises assembling the upper, sole and sock lining of a slipper, securing less than the entire length oi said lining to said upper by a row of stitches I passing through all three of said elements, continuing said row of stitches to attach the remaining length of the sole to said upper, supplying apadding formed oi two layers of material stitched together partly around their edges to form a pocket, and forcing said padding between said lining and sole by inserting an implement into said pocket.

3. The method of making slippers which comprises securing together the upper, sole and sock lining of a slipper while said elements are in a reversed position with the upper interposed between the sole and sock lining, turning said elements to their normal position, supplying a padding formed of two layers of material stitched together partly around their edges to provide a pocket, forcing said padding between said lining and sole by utilizing an implement introduced into said pocket, and encasing an unstitched part 5 of said padding within a portion of said lining.

4. A slipper comprising an upper, a sole, a sock lining, means securing all three of said elements together, and a padding inserted between sai-d sole and lining and having a pocket therein l0 the closed end of which terminates at the toe portion of the padding.

5. A slipper comprising an upper, a sole, a sock lining, means securing all three of said elements together, and a padding inserted between said sole and lining, said padding consisting of two superimposed layers of material the forward portions of which have their edges secured together and the rear portions being unattached.

6. A slipper comprising an upper, a sole, a sock lining, means securing all three of said elements together, a padding inserted between said sole and lining, said padding consisting of two superimposed layers of material the forward portions of which have their edges secured together and the rear portions being unattached, and said sock lining having a recess for receiving and enclosing one of the rear portions of said padding.

'7. A slipper-comprising an upper, a sole, a 30 sock lining, means securing all three oi said elements together, a padding inserted between said sole and lining, said padding consisting of two superimposed layers oi material the forward portions of which have their edges secured together and the rear portions being unattached, said sock lining having a recess for receiving and enclosing one of the rear portions of said padding, and a shank stiifener positioned between said rear portions of said padding. 40

8. A padding for use in slippers and adapted for insertion between the sole and sock lining of a slipper, sai-d padding comprising two layers of material the edges of which are secured together for only a portion of the total length of the padding.
